Montana US 93 Dawn's Crossing Bridge

Primary tabs

Seven cameras were placed at a highly used wildlife crossing bridge to learn more about the full spectrum of animals using the structure, other than the larger animals moving just past the one camera that has been on the structure since 2008.

One Spartan go-cam cell phone communicating camera was placed to monitor large animals. Six Bushnell camera were placed in various places to capture other animal movements. One camera was placed up in the supports of the bridge where there was evidence of bat activity. One camera was placed on the underside of the bridge to monitor small mammal movement on the berm under the bridge. The remaining four cameras were placed at ground level on two of the corners of the bridge entrances. One was placed at ground level to capture small and medium animals. The goal was to compare the results from these seven cameras with the results from the single camera that monitored the structure long term.
